i waiting, to get it, it comes out in 2 weeks.
Its a awesome game, the demo dose not show how good this game will be, and how you can sorta do anything.
My Friend has a copy from overseas, and its very playable, but there is a few bugs.

Yeah i'll be getting it to, i enjoyed the demo, it was buggy and ran sluggish on my system but was still alot of fun, no doubt the retail version will be more polished so im looking forward to it especially some co-op action
Gameswarehouse site has release date of march 8th

Physics are allot better than OFP, but its nothing as obvious as Half life 2.
Choppers are harder, and will take practice.
The bugs in physics are due to the way its done i think, like blowing up a bridge with a car on it not moving, and the car floats in mid air.

Parts of the game feel very unfinished. One of the bases has objects floating just above the ground as well as sand bag walls sticking out of the floors inside houses. There is one mission where you start in a house with a friendly soldier standing in the hallway blocking the only door out. Sometimes he'd move out of the way, other times he'd block the only path out, forcing you to shoot him or restart till he moved. I can't count the number of times I've seen helicopters crash into trees, mountains, powerlines, buildings or other helicopters. In another mission I had to pick up some troops in a truck but they wouldn't get in. I had to board a Stryker and get driven about 100m out of the base and down a runway, the driver did a 40 point turn (zig zagging on the spot) crashed into a wall and then wedged the Stryker between the wall and a building. You have to work pretty hard to screw up a waypoint travel script.

Hopefully they can fix the problems cause it'd be a brilliant game once polished.
